Rcpp 0.7.3

January 21, 2010

(This article was first published on Thinking inside the box , and kindly contributed to R-bloggers)

A quick nine days after
release 0.7.2
of Rcpp,
our R / C++ interface classes,
Romain and I are happy to roll out a new
version 0.7.3.
It has been uploaded to
CRAN and
Debian, and mirrors should have the new
versions shortly. As before, my local page is
also available for downloads and some more details.

This release combines a number of under-the-hood fixes and enhancements with
one bug fix:

  • The Rcpp:::LdFlags() helper function to dynamically provide
    linker options for packages using
    Rcpp now defaults
    to static linking on OS X as well. For installation from source dynamic
    linking always worked, but not for binary installation (as e.g. from
    CRAN). As on the other platforms,
    this default can be overridden. Thanks to the
    team for patient help in tracking this down.
  • Accessing various types via [] should now be faster due to some
    enhancements in the internal representations.
  • configure now has a command-line option (as well as an
    environment variable) to select support for the draft of the upcoming C++0x
  • A new function Rcpp.package.skeleton(), modelled after
    package.skeleton() in R itself, helps to set up a new package
    with support for using
  • A number of other minor tweaks and improvements…

As always, full details are in the ChangeLog on the
Rcpp page which also
leads to the downloads, the
doxygen docs
and zip files of doxygen output for the standard formats.
Questions, comments etc should go to the
rcpp-devel mailing list
off the R-Forge page
